How To Install a Honeywell Wi-fi Thermostat
Congratulations! You’ve made the decision to upgrade to a Wi-Fi thermostat. You’ll now have smarter control over your home’s temperature, and be able to access the thermostat controls from anywhere.
But first, you need to know how to install a Honeywell wi-fi thermostat. Here’s our guide to installing the thermostat, from start to finish.
How to Install a Honeywell Wi-Fi Thermostat
The installation process involves three primary steps:
- Removing the old thermostat.
- Connecting the new device.
- Setting up the thermostat’s controls.
Removing the old thermostat
Before you take any steps to dismantle the device, turn off the power to the HVAC system and the thermostat by switching off the corresponding breaker on the home’s circuit breaker panel. Now, you’re ready to begin.
Now, gently coax the thermostat’s front-facing panel off the mount, being careful to keep the wire connections intact.
Once it’s removed, you’ll see a variety of wires of differing colors connected to the terminals. The new thermostat should include wiring labels. Use these to label each wire (explained in the steps below) so you can later correctly install the wires to the new thermostat’s terminals. Instead of labeling the wires, you can also take a picture of the wiring for later reference. However, don’t remove the wiring to apply the labels; simply pull each one of the wires out gently to get enough clearance to wrap the label around it.
You’ll need to identify the “C” wire or the wire that provides power to the thermostat, as it doesn’t run on batteries.
Identify the jumper wire, which is designed to connect the “R” and “RC” wires. Label this wire.
Continue labeling the wires based on the corresponding letters. For example, apply the “G” label to the “G” wire.
When you’re finished labeling the wires, you can proceed to the next step.
Using a screwdriver, loosen the terminals so that the wires are no longer connected, and remove the wall plate of the old thermostat, too.
Gather the wires coming out of the hole in the wall, and give them a twist to prevent them from slipping back into the wall. Be careful that the labels don’t come off in the process.
Connecting the new thermostat
Now, since you’ve learned how to install a Honeywell wi-fi thermostat, it’s time to install your new thermostat.
Remove the packaging from the thermostat, and make sure you have all of the components identified in the manual, such as the user guide, wall anchors, and so forth.
Work in reverse to install the wiring.
Take the thermostat and separate the wall plate from the front. Put the wall plate on the wall, making sure it’s level. Secure the wall plate using the screws.
Look at the plate and start connecting the wires to the corresponding terminals. Then, tighten the screws to the terminals.
If the wiring is not taut, gently push the wires into the center of the wall plate so you can put the cover on.
The Wi-Fi thermostat comes with a cell battery that looks like a coin. Insert it into the slot on the bottom right-hand corner.
Put the cover on.
Restore power to the thermostat and HVAC system.
Now, the thermostat’s digital display should come on, meaning that the unit has power.
Setting up the thermostat’s controls
It will take you some time thumbing through the user guide to get the thermostat functioning fully, but there is one function you should set up immediately. You must first set the “system type” function before you can proceed with setting up the Wi-Fi connection. It also helps to ensure the HVAC systems will work properly, too.
Here’s what to do:
- Press “system.”
- Hold down the middle button on the bottom of the screen. (All of the buttons at the center bottom are intentionally blank.)
- Continue holding it long enough for the screen to change.
- Then, select function 0170 by scrolling through the “up” or “down” arrows.
- The default setting is for a single-stage furnace and air conditioning. If you have another system type, such as a two-stage HVAC or heat pump, keep scrolling through the arrows until you see your system type. The user manual will also list the types of systems with their corresponding code.
- Once you’ve found your system type, press “done,” on the left-hand, lower side of the screen.
- You can now follow the user manual to set up the date and time and the Wi-Fi connection.
